3D model description

These fan covers were designed to fit the standard 40mm part cooling fans that come stock with many Ender series printers (and perhaps some others). They snap into place with no additional fasteners needed, following the mantra of the Minimus Hotend Cooler System, "No Screws"! The covers are non-handed.

These fan covers are the companions of my hotend fan covers for the Minimus system:

These may also fit the Winsinn 40mm part cooling fans, but I don't have any to test. Let me know in the comments if they don't fit, and I'll work on getting covers for those too.

3D printing settings

I would recommend printing these in PETG if you can, just because the snap fit features will be more robust, but PLA should be just fine as well.

Make sure you've got your retraction/stringing dialed in as there are some small features. The posts for the fan mounting holes are 2mm in diameter. The side snaps and designs which cover the fan are only 1.2mm wide.

I would recommend slowing down your first layer to help with the designs which cover the fan, especially if you're using the polygons cover.
